Hello Debian Kernel Maintainers,

TL;DR: please enable CONFIG_PINCTRL_METEORLAKE=y in kernel config


I recently bought an MSI laptop, Micro-Star International Co., Ltd. 
Prestige 16 AI Studio B1VEG/MS-15A2, BIOS E15A2IMS.10A 01/29/2024 which 
uses Intel Meteor Lake Core Ultra CPU, which is fairly new.

I installed debian stable out of the box and a lot of hardware did not 
work. A lot of this was resolved by installing upstream firmware but the 
debian stable kernel is too old sadly. I upgraded to bookworm-backports 
kernel-image (6.6.13) but was still stuck on 800x600 display, no 
touchpad. I installed the kernel-image from SID (6.7.9-2) which resolved 
the graphics issue but the touchpad was still not working.

I installed fedora 39 and the touchpad was working fine, so I compared 
the kernel config between the 2 distros and after a little trial and 
error found that:

CONFIG_PINCTRL_METEORLAKE=y

must be set in order for touchpad to work. Please consider enabling this 
option in the debian kernel config as it may help others.


Thank you
